A 9 shot average came out to be 2116fps. Pretty happy with the gun so far. Looking forward to getting dies and seeing what I can do with it.
For those of you who know, are all the 450b Ruger bolt actions 1:16 twist, including the 22 incher? I'm trying to wrap my head around the fact that the 22" barrel turned out speeds a little less than what I've seen posted by members running shorter, semi-auto 1:24 rigs. Now ball powders are infamous for tracking temperatures both up and down, so that could be the issue. That having been said and assuming they're all 1:16, then perhaps the faster twist takes a toll on longer barrels. Does not compute!
However, that's the first documented example I've ever seen in this caliber of factory loads below 2200 fps in a non-carbine length barrel. I never shot a 450b load that was chronied in warm weather, once it got below freezing since I'm not found on a range below about 45 degrees.
